Boston police said they are also probing a possible link to Hernandez in the unsolved July 2012 drive-by killings of Safiro Furtado and Danny Abreu, both of Dorchester. The two pals were leaving a Theatre District nightclub July 15, 2012, when they were ambushed and sprayed with gunfire from a gray or silver SUV with Rhode Island plates at the intersection of Shawmut Avenue and Herald Street.

Boston police were back at Hernandez’s North Attleboro home last night executing a new search linked to the double murder.

Evidence against Hernandez continued to mount yesterday as Bristol County Assistant District Attorney Bill McCauley said investigators found a .45 caliber clip in Hernandez’s Hummer at his Franklin condominium. Authorities say Lloyd was coldly gunned down with a .45 caliber semi-automatic handgun just before 3:30 a.m. June 17 on a dark, gravel road about a half-mile from Hernandez’s house.

McCauley also referred to a widely circulated picture on the Internet of Hernandez posing with a Glock .45 and said, “There’s good reason to believe that the firearm that killed Mr. Lloyd was a Glock.”

Authorities also charged Carlos Ortiz, 27, with illegally possessing a gun at Hernandez’s home on the morning of the murder. Ortiz is from Hernandez’s hometown of Bristol, Conn.

Also last night, police issued a wanted poster for one of Hernandez’s alleged accomplices, Ernest Wallace, 41, who was called “armed and dangerous.”
